"BCD enables integration of bipolar, logic, and high-voltage circuits on a single chip. The benefit of this level of integration will enable new innovation in the next generation power-management products* k5 J q- k1 e1 A0 P
Power-management ICs will benefit from having OTP/MTP for trim, calibration and secure key and code storage to improve performance and yield at low cost."

這是從某個fab節錄下來的 請問一下 power management真的有需要儲存secure key跟 code嗎? 因為這些通常都在digital部分 若有 這個secure key是在做啥種保密的?(ex. TV 有HDCP, SD有CPRM...)那code 又是儲存啥功能的程式碼 ? size大概需要多大 ? 需要erase的次數大概多少次?
